Description

Steel bar girder beam form frame and H section steel beam-cast-in-place concrete floor formwork system
Technical field
The utility model relates to a kind of building operations mould bases and formwork system, relates in particular to a kind of Simple reinforced bar girder truss mould bases and H section steel beam-cast-in-place concrete floor formwork system.
Background technology
At present, the floor floor such as super highrise building mechanical floor, refuge story all adopts H section steel beam-cast-in-place concrete floor.For the above-mentioned floor of constructing, conventional steel scaffold mold method exists that workload is large, efficiency of construction is low, and material tool is had bad luck the construction technology difficult problems such as difficulty, high-altitude formwork potential safety hazard are large.
Summary of the invention
The purpose of this utility model is to provide a kind of Simple reinforced bar girder truss mould bases, to effectively solve the technical barrier of construction Super High H section steel beam-cast-in-place concrete floor.
The utility model is realized by following technical proposals: a kind of steel bar girder beam form frame, and it comprises upper chord, lower chord, perpendicular web member, diagonal web member and pull bar, described pull bar is welded between two lower chords; Described perpendicular web member is welded in two ends and the centre of described upper and lower chord member, forms equilateral triangle with described pull bar; Described diagonal web member and upper and lower chord member be drawknot respectively, forms triangle support frame together with described equilateral triangle.
Equilateral triangle length of side a described in the utility model equals 300mm.
Each bar described in the utility model all adopts C20 reinforcement fabrication.
The utility model further provides a kind of H section steel beam-cast-in-place concrete floor formwork system, it comprises steel bar girder beam form frame as above, H section steel beam, short flitch, triangle timber wedge, flitch keel and template, described steel bar girder beam form frame length is chosen according to H section steel beam spacing, described steel bar girder beam form frame two ends are placed on respectively on adjacent twice H shaped-steel-beam upper wing-edge plate, cushion block is made with described short flitch in described steel bar girder beam form frame lower end, between described short flitch and described steel bar girder beam form frame, place two described triangle timber wedges, for clamping from both sides and fine setting absolute altitude, described flitch keel and described template are laid in described steel bar girder beam form frame top.
While adopting the utility model to construct, workload greatly reduces, and has improved operating efficiency, has eliminated the potential safety hazard of high-altitude formwork, has effectively solved the technical barrier of construction Super High H section steel beam-cast-in-place concrete floor.

Detailed description of the invention
Below, with reference to the accompanying drawings of embodiment of the present utility model.
Referring to Fig. 1, steel bar girder beam form frame of the present utility model adopts the welding of C20 reinforcing bar, is divided into the triangle support frame 6 of the length of side a=300mm that lower chord 1, upper chord 2, perpendicular web member 3, diagonal web member 4, pull bar 5 form.Between two lower chords of bottom, increase pull bar, middle and two ends arrange perpendicular web member, and diagonal web member and upper and lower chord member be drawknot respectively, form overall space rock-steady structure system.
Referring to Fig. 2,3, H section steel beam-cast-in-place concrete floor formwork system of the present utility model, its steel bar girder beam form frame is that triangular supports 6 is equivalent to shuttering supporting, have the effect of template main joist concurrently, when formwork, only need construction operation personnel with rope, it to be sling from ground, spacing 900mm is placed on adjacent twice H section steel beam 7 bottom wing listriums, cushion block is done with short flitch 8 traverses of 45 long × 95mm of a 600mm in steel bar girder beam form frame lower end, between this cushion block and steel bar girder mould bases, clamps and levelling from both sides with two 200mm Yangtze River Delta shape timber wedge 9.Flitch keel 10 are as secondary joist, select the flitch of 45 × 95mm, spacing 150mm is positioned on Simple reinforced bar girder truss mould bases, and template 11 selects the wood glue plate of thick 15mm to be placed on flitch keel, has so just formed complete H section steel beam-cast-in-place concrete floor formwork system.
